Conflict of Interest for IMF Candidate Christine Lagarde?

Related to my last post, I wanted to show this video of Agustin Carstens talking about his IMF candidacy...In previous occasions he has mentioned that he will bring a 'fresh set of eyes' to the IMF presidency, and states that having French Finance Minister Christine Lagarde as head of the the IMF is comparable to 'starting a soccer match at 5-0'. Is it fair to have the main borrowers head-up the crediting institution?

Tell me what you think.
